Understanding anatomy and physiology is crucial for nail technologists because it helps them comprehend the structure and function of the nail and surrounding tissues. Knowledge of nail anatomy, including the nail plate, nail bed, cuticle, and nail matrix, enables technicians to provide safe and effective services, such as manicures, pedicures, and nail enhancements. Additionally, understanding physiological processes like nail growth and response to trauma or disease allows technicians to identify potential issues and take necessary precautions to prevent damage or infection. This knowledge ensures that nail technicians can deliver high-quality services while maintaining client safety and well-being.
